SpaceX’s Falcon 9 rocket and a variety of satellites have already flown on previous missions to the International Space Station.
Now the company is ready to take its first test flight in the future.
A rocket launch is expected for mid-June, when the company will blast off from Cape Canaveral, Florida.
The rocket will carry an assortment of cargo, including three communications satellites.
The first stage will lift off in the early afternoon.
SpaceX is hoping that the rocket will be able to achieve a height of just over 50 feet (15 meters), which would be about the height of a passenger jet.
The Falcon 9 is expected to make the trip at a speed of more than 7,000 miles per hour (11,000 kilometers per hour).
It is also expected to achieve an altitude of more to 10,000 feet (3,000 meters).
SpaceX says the rocket can reach an altitude from 10,700 feet (4,300 meters) to as high as 30,000.
The company has not yet set a launch date.
In April, SpaceX successfully launched a rocket that was capable of carrying four people, including an American, into orbit.
